High Quality 20*100mm strong neodymium bar magnets

20*100mm strong bar magnets

 Permanent magnetic bars and grate magnets are designed to remove ferrous metal and tramp iron from free-flowing materials such as plastics, foods, cosmetics, grains and minerals.Our high-density permanent magnetic tubes/bars 
are arranged in grate magnets to draw iron particles into 
the magnetic field and hold them there as material flows through the grate. Two styles of grate magnets 
are available in round or rectangular/square models to best suit your needs. Both are constructed of stainless steel
 with different diameter magnetic tubes/bars placed to provide the greatest magnetic efficiency. Tubes are filled with 
Rare Earth magnetic material. Deflectors are placed to direct product flow across the strongest magnet

1. Physical Properties of Neodymium Magnet:

a.NdFeB Magnets are the strongest magnets in the world. They can lift up to 1000 times theirs own weight.

b.NdFeB Magnets are easy to machine, compared to Alnico and SmCo magnets.

c.NdFeB Magnets are with high resistance to demagnetization.

2. application

Widely used in generators, DC motors, servo motors, Speakers, receivers, VCM, CD/DVD-ROM, magnetic

separation, magnetic cranes, magnetic lifters, magnetic filters, nuclear magnetic resonance spectrometer,

medical equipment, etc.
